I recently purchase a new BX2380 tractor. The dealership dropped it off at my home. Later I realized that one of the MMM pins was missing. The dealership over 40 miles away sent me a new pin, spring, and push in pin. Any tip to installing it. I am an 82 year old man with balance issures. I cannot crawl under without having days of balance issures due to a previous stroke. Do I have to hammer the pin in, or can it be squeezed tight and slid in. Will the main pin go in through the outer hole, then the spring, and pin or some other way. I would never ask this question if I didn't have the balance issue.
